Hi... I'm seeing a problem using Ultra wide SCSI with a pair of 9G Viking II drives. The symptoms are read timeouts and bus resets. And inevitable data corruption. The problem goes away if I change the negotiation to Fast SCSI (20MB/s). I've tried a different 958, different cable and different drives. So I suspect the motherboard or the driver at this stage. Can anyone offer any clues? The motherboard is... I've forgotten. Some recent genuine Intel 440BX chipset thing with a Celeron 333 slot 1 CPU and 224 meg of RAM.
